Background technology
The charger for electric bicycle of Chu Shouing does not possess the function of reporting to the police and cutting off the charger power supply automatically owing to the smog that produces before various imflammable gas and the fire formation in the market, therefore, when running into above-mentioned situation and take place, often can not detect dangerous situation and the generation of termination dangerous situation in time in time, thereby cause damage for people's property and even life.
Summary of the invention
In order to overcome the deficiency that above-mentioned known charger for electric bicycle exists, the purpose of this utility model, be to provide a kind of charger for electric bicycle with smog alarm, this kind charger adopts semiconductor gas sensor as transducer, realize that " gas-" transition trigger is reported to the police and the J relay cuts off charging circuit, can be to such as coal gas, natural gas, gasoline, alcohol, imflammable gas and timber such as ethers, paper, cotton, woolen, rubber, the smog that produces before fire such as plastic products and oils forms is reported to the police, and cuts off the charge power supply of charger simultaneously.
The technical scheme that realizes the utility model purpose is such:
A kind of charger for electric bicycle with smog alarm, comprise power supply, charging circuit, it is characterized in that: described charger for electric bicycle also has smog supervisory circuit, warning circuit and charging power-down circuit, the output that the input of described smog supervisory circuit is connected to power supply, smog supervisory circuit is connected respectively to the input of described warning circuit and the input of charging power-down circuit, is connected to the input of charging circuit after the output parallel connection of the output of this warning circuit and charging power-down circuit.
Described smog supervisory circuit adopts semiconductor gas sensor as transducer, realizes " gas-" conversion, and with time-base circuit composition triggering warning circuit.
Described charging power-down circuit is made up of relay circuit.
The charger for electric bicycle with smog alarm that the utility model provides is by increasing smog supervisory circuit and warning circuit and charging power-down circuit in existing charger, adopt semiconductor gas sensor as transducer, conversion Ic555 time-base circuit is formed circuits for triggering and alarm sound circuit and J relay cut-out charging circuit to realize " gas-", can be to such as coal gas, natural gas, gasoline, alcohol, imflammable gas and timber such as ethers, paper, cotton, woolen, rubber, the smog that produces before fire such as plastic products and oils forms is reported to the police, cut off the charge power supply of charger simultaneously, avoided the further expansion of fire.
